(一)LTE D2D/V2X
车联网V2X通信是基于D2D的一种侧行链路传输技术。与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同,车联网系统采用终端到终端直接通信的方式,因此具有更高的频谱效率以及更低的传输时延。D2D/V2X可采用两种传输模式:模式A和模式B。
模式A:如图2A所示,终端210(例如车载终端)的传输资源是由基站220分配的,终端210根据基站220分配的资源在侧行链路上进行数据的发送;基站220可以为终端210分配单次传输的资源,也可以为终端分配半静态传输的资源。
模式B:终端(例如车载终端)在资源池中选取一个资源进行数据的传输。如图2B所示,在一些场景中,基站220可以不为终端210分配资源。
适应于各类业务的快速发展,D2D技术包括以下发展阶段:
阶段1、基于距离的服务(Proximity based Service,ProSe):该阶段中,设备到设备通信是针对ProSe的场景进行研究,其主要针对公共安全类的业务。
在ProSe中,通过配置资源池在时域上的位置,例如资源池在时域上非连续,实现UE在侧行链路上非连续发送/接收数据,从而达到省电的效果。
阶段2、车联网(V2X):针对车车通信的场景进行了研究,其主要面向相对高速移动的车车、车人通信的业务。
在V2X中,由于车载系统具有持续的供电,因此,主要问题不是功率效率,而是数据传输的时延。因此,在系统设计上要求终端设备进行连续的发送和接收。
阶段3、进一步增强D2D(Further Enhancements to LTE Device to Device,FeD2D):对于可穿戴设备通过手机接入网络的场景进行了研究,其主要面向是低移动速度以及低功率接入的场景。
在FeD2D中,一种可选的实现方式是:基站可以通过一个中继(relay)终端去配置移动终端的非连续接收(Discontinuous Reception,DRX)参数,但并未对DRX配置的方式进行标准化。
(二)NR V2X
NR V2X在LTE V2X的基础上,不局限于广播场景,而是进一步拓展到了单播和组播的场景,在这些场景下研究V2X的应用。
NR V2X支持与LTE V2X中模式A和模式B类似的两种资源授权模式:模式1和模式2(mode-1/2)。更进一步地,用户可能处在一个混合的模式下,即既可以使用模式1进行资源的获取,又同时可以使用模式2进行资源的获取。该资源获取通过侧行链路授权的方式指示,即侧行链路授权指示相应的物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)与物理上行共享信道(Physical Sidelink Shared Channel,PSSCH)资源的时频位置。
不同于LTE V2X,除了无反馈的、UE自主发起的混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)重传,NR V2X还引入了基于反馈的HARQ重传,不限于单播通信,也包括组播通信。
与LTE V2X相同,在NR V2X中,由于车载系统具有持续的供电,因此功率、效率不是主要问题,而数据传输的时延是主要问题,因此在系统设计上要求终端设备进行连续的发送和接收。
(三)NR定位技术
位置是目前生活中不可或缺的应用之一,大家对于定位的延迟和准确性要求也越来越严格。在许多定位应用中,精确定位通常是通过多种技术的组合来实现的,例如以下技术:
1)基于全球导航卫星系统(Global Navigation Satellite System,GNSS)提供户外场景中的位置信息;
2)无线电技术(例如LTE网络,通过提供多种选项来定位用户,包括无线网络、地面信标系统等等);
3)惯性测量单元(Inertial Measurement Units,IMU)或传感器(例如基于加速计追踪用户位置,基于陀螺仪、磁力仪或利用大气压力传感器进行垂直定位)。
这些技术都有望在未来实现准确的用户定位方面发挥重要作用。
NR的增强定位能力能为定位准确性带来额外的增益。低频段和高频段(即FR1和FR2)的操作和大量天线阵列的使用提供了额外的自由度,大大提高了定位精度。基于到达时间差定位法(Observed Time Difference of Arrival,OTDOA)和上行链路到达时间定位法(Uplink Time Difference of Arrival,UTDOA)、小区识别码(Cell Identifier,Cell-ID)或E-Cell-ID等定位技术,利用大带宽(低频段以及高频段)进行时间测量为用户定位带来了更好的性能。利用大规模天线系统例如大规模(massive)多进多出系统(Multiple Input Multiple Output,MIMO),通过结合时间测量以及传播信道的空间和角度域来实现更准确的用户位置。
(四)定位完整性(Positioning Integrity)
每次提供位置时,都可以使用定位完整性来量化对所提供位置的信任度。因此,定位完整性检查是限制定位误差的一种方法,并且可以以更高的置信度完成此操作。
定位完整性涉及的关键绩效指标(Key Performance Indicator,KPI)包括:
1、目标完整性风险(Target Integrity Risk,TIR),即定位错误超出警报限制(Alert Limit,AL)而未在要求的警报时间(Time-to-Alert,TTA)内警告用户的概率。
TIR通常定义为每个时间单位(例如,每小时、每秒或每个独立样本)的概率。
2、警报限制(AL),即允许的最大定位误差,以便定位系统可用于预期应用。如果定位误差超出AL,则应声明定位系统对预期应用不可用,以防止定位完整性的损失。
注意:当AL限制水平面或垂直轴上的定位误差时,分别称为水平警报限制(HAL)或垂直警报限制(VAL)。
3、警报时间(TTA),从定位误差超过警报限制(AL)到提供定位完整性的功能发出相应警报的最大允许经过时间。
4、完整性可用性,完整性可用性是保护级别(Protection Level,PL)低于所需AL的时间百分比。
5、保护级别(PL),是定位误差(PE)的统计上限,它确保每单位时间内真实错误大于AL且PL小于或等于AL的时间长于TTA的概率小于所需的TIR。
图3示出了完整性事件的示意图。如图3所示,定位完整性的检查结果包括:
1、系统可用(PL<AL),包括:
标称运行(PE<PL):解决方案可用且安全运行,没有完整性事件。
误导信息(PE>PL且PE<AL):解决方案可用,但由于PE>PL,因此包含MI(PE>PL)完整性事件。鉴于PE不超过AL,它仍在安全运行。
危险的误导信息(PE>PL且PE>AL):解决方案可用,但由于PE>AL,因此包含HMI完整性事件。当它不应该被声明为安全时,它仍然被声明为安全的(PL<AL)。
2、系统不可用(PL>AL),包括:
系统不可用且错误警报(PE<PL且PE<AL):解决方案不可用,是错误警报完整性事件,给定PE<AL。
系统不可用(PE<PL且PE>AL):如果正确检测到PE>AL,则解决方案不可用并且在没有完整性事件的情况下按预期运行。
系统不可用且具有误导性(PE>PL且PE>AL):解决方案不可用且包含MI(PE>PL)完整性事件。
经本申请发明人深入研究发现,目前NR定位实现方式仍然不够灵活。引入SL定位技术可以提高定位实现方式的灵活性,示例性地,可以以SL用户为定位锚点。如何确定SL用户的定位锚点是需要研究的问题。
本申请实施例提供的方案,主要用于解决上述问题中的至少一个。
为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。

S410:侧行链路中的第一电子设备基于第一电子设备的锚点相关信息,向侧行链路中的第二电子设备发送第一消息,其中,第一消息用于指示第二电子设备确定定位锚点。
根据该方法,在侧行链路中,第一电子设备基于自身的锚点相关信息向第二电子设备发送消息,以指示第二电子设备确定定位锚点。如此,各电子设备之间通过侧行链路交互锚点相关信息,有利于各电子设备利用侧行链路上的其他电子设备得到定位锚点,提高定位实现方式的灵活性,以进一步提升定位精准度。

又如,定位完整性检查由定位管理功能执行,指标参数也可以由第一电子设备或其他电子设备决定。若为第一电子设备决定,则第一电子设备向定位管理功能发送指标参数。
实际应用中,基于锚点相关信息发送第一消息,可以包括基于锚点相关信息触发第一消息的发送,或者根据锚点相关信息确定第一消息的内容以发送第一消息等实施方式。以下提供两种示例:

示例性地,第一电子设备若判断其为有效锚点,可以发送肯定信息给第二电子设备,或直接发送第二电子设备定位所需的PRS给第二电子设备,以告知其为有效锚点。第一电子设备若判断其不是有效锚点,则发送否定信息给第二电子设备。
